Being forced to exercise may still help reduce anxiety and depression just as exercising voluntarily does, according to a new study by researchers at the University of Colorado Boulder.

Past studies have shown that people who exercise are more protected against stress-related disorders. And scientists know that the perception of control can benefit a person's mental health. But it has been an open question whether a person who feels forced to exercise, eliminating the perception of control, would still reap the anxiety-fighting benefits of the exercise.
